The downloadable PDF is best viewed using Adobe Acrobat—either the full version or the free Adobe Reader.

As a PDF, the digital edition may be viewed on most tablet computers, although it is seriously compromised on non-color devices, such as the original Kindle and Nook, and is cumbersome to read on small smartphone screens.

Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
